Simon Stephan

Research Scientist in the field of Cognitive Science at the University of Göttingen

About me

I am a post-doctoral researcher at the University of Göttingen working in Michael Waldmann’s Lab of Cognitive and Decision Sciences. I’m interested in human causal learning and reasoning. Given that causal relationships are neither directly observable nor logically deducible, how do reasoners manage to learn about causes and effect so successfully? How do they use this knowledge to make predictions, diagnoses, or to explain things?

On this website I share information about my academic life. You’ll find things like an up-to-date CV, my publication list, and information about recent/ upcoming presentations (e.g., conference talks).
